Don't overdo it but provide for major sections and document the accesskeys in an accessibility statement;

NB: be careful with the choice of accesskeys because they can cause conflicts with browser software and adaptive technology. This situation is unfortunate as it limits the usefulness and memorability of the accesskeys. A safe option is to use the keys recommended by the UK government in their accesskey standard (see list in examples section), or generally just numbers.

Skip code examples (this bypasses the code below - a timely example that avoids screen reader users having to listen to all the code if they don't want to).
